The controllers are done to-scale with approximated measurements. Using a USB port in the video, a clever user (I don't have their name) was able to get the measurements of the tablet's screen, and by extension, the Joy-Cons. There are no Joysticks on the Joycons, as this is simply to show scale for the unit, as a lot of people are concerned about the size. The unit is not intended to attach together. The Joy-Cons are also missing a trigger.
